I just bought my new Razer Naga 2014 yesterday and to my surprise it didn't work. It doesn't light up, nor does it move or click. I have tried using all my usb ports to no luck (and yes the usb ports work). My pc picks up that something is there, but the mouse it classified as an unspecified device. I thought maybe i just have to download the drivers for the mouse, but Razer Synapse 2.0 (razers driver and settings -program for many of their products) will not recognize the naga. It is stuck at the screen that says: "please connect a razer synapse 2.0 enabled device". The mouse works perfectly with my brothers pc (also a laptop), so i tried updating the mouse from there with razer synapse. Still didn't fix anything. The weird part is that i have a razer keyboard aswell and when i boot my pc the keyboard and mouse light up at the same time. Then they suddenly stop at the same time, but the keyboard is the only one that lights up again after that.
